CHEMETAL USA is a respected manufacturer and worldwide supplier of tungsten plates, tungsten sheets, and a wide variety of their milled end products. We are capable of machining tungsten plates and sheets within a range of thickness from 10 inches (25.4 cm) to less than 0.004 inches (0.1 mm). All our products meet stringent quality control standards at every stage of production, from rolling and annealing to surface treatment and testing.

Each tungsten plate or sheet is produced to exacting standards of performance, purity, dimension, flatness, and surface condition. Tungsten plates and sheets, sometimes alloyed with other metals, are compacted and sintered into ingots by powder metallurgy. The ingots undergo a further series of heatings, rollings, and millings to yield finished products per customer specifications.

    Our knowledgeable engineers work closely with our customers to tailor the product’s parameters to the customer’s requirements. The tungsten plate products offered by CHEMETAL USA are under close inspection and quality control of the microstructure, recrystallization behavior, the mechanical, chemical, and physical properties. We worked hard to optimize the sintering and rolling processes in order to cost-effectively achieve a high production yield and homogenous microstructure.


    Tungsten Alloy Plate And Sheet (WNiFe, WNiCu, WCu)

    WNiFe, WNiCu Plate And Sheet

    Tungsten heavy alloy plates and sheets contain 80%-98% tungsten and small amounts of molybdenum, nickel, iron, and copper. As with pure tungsten plate, this alloyed product begins as powders that undergo heating, mixing, pressing, and sintering, resulting in a metal alloy with unique industrial properties.

    For example, tungsten plate’s high density (16.5-19.0 g/cc), low thermal expansion, corrosion resistance, and high thermal and electrical conductivity make tungsten heavy alloy ideal for use in many aerospace, military, and medical applications. Its hardness and wear resistance are important in the manufacture of machining tools, including lathes and dices. And its ability to absorb radiation is critical to maintaining high performance in radioactive environments. More about tungsten heavy alloy plate and sheet>>>


    Tungsten Copper (WCu) Plate And Sheet 

    Tungsten copper plates and sheets are preferred flat materials for high voltage and high temperature applications, resistance welding, and EDM applications. This is due to its excellent thermal and electrical erosion resistance, as well as its conductivity, low thermal expansion, and good machinability. Pure tungsten has a high thermal strength and melting point. Copper has an excellent thermal and electrical conductivity and is also much easier to machine than tungsten. Tungsten copper plate and sheet consist of tungsten and copper at varying W and Cu ratios which mainly includes 50/50, 60/40, 70/30,75/25, 80/20, and 90/10.  The wide range of ratio compositions allows copper tungsten materials to be easily tailored to conform to distinct physical and mechanical properties upon different requirements.
